Selecting a suitable metal detector can be a very difficult task and you could make a costly mistake. Find metal detectors for the purchase is easy, but finding information that is useful is not so easy.

Most magazines are full of exploration ads touting the company manufactures the metal detector and you'll be rich if you just get this model. How true are their claims? Is a specific model to help you find more treasure?

The truth of the matter is that luck plays a big role in the treasure hunt. Regardless of the metal detector you have, if you are not the right place at the right time, you will not find anything.

However, having the right equipment and knowledge can help you in the right place more often.

What do you look for?

This is a very important question to ask. What you normally do, and what kind of gold is in your area? Have you been to find nuggets in a particular area or you are simply looking for an extra edge while panning?

If you are a casual prospector, then you can not even need a detector. If you decide that it can be fun, then a model that can also be used to find coins on the beach can be a better choice for you.

If you were to find nuggets, then you want to get a gold detector specific, as it will be fine for your application, finding nuggets.

Another thing to keep in mind is the field that you normally search in. If you are planning a serious hiking, you may want a body mounted sensor, so that your hands are free. If you work streams, then you want a tight coil and detector. If the soil is dense and highly mineralized, you may need a detector with better filtering capabilities of a standard model.

Do your homework first

Technology is constantly evolving, and even the most advanced detectors of a few years ago are virtually obsolete today. It is important to know which models are truly new and improved, and which are just repackaging of outdated designs.

Updating old designs is often accomplished by adding microprocessors or LCD screens. This can make a detector more pleasant to use, but adds little or nothing to their real capacity.

People are often inclined to be loyal to a particular brand. However, this can be a serious mistake if a superior performance with a better warranty may be obtained elsewhere.

Change in technology can quickly overcome the experience, do not assume you know everything. Do your homework. Knowledge is the best substitute for experience.

How does a switch work?

Metal detectors indicate the presence of metal. A metal detector works by creating a magnetic field that is used to load the zone below its coil. As the field moves in front of an underground object, it reacts to the magnetic field through the creation of his own domain. The sensor detects the tiny fields and tells the operator that there is something metal and what type of metal, it can be.

There are two types of common sensors.

Very low frequency (VLF) models are the most common and work very well. A nice feature is that they often have very good discriminator circuits. This keeps the detector can find pop tabs, when you are looking for parts.

Soil type is desired limits VLF detector efficiency. If there is mineralization, such as salt, the scope of the detector will be reduced.

Pulse Induction (PI) function to send a strong push into the ground and measuring the time it takes for the field to rot. If it takes more than a few milliseconds, then there is something metal in the box below. Different metals retain the pulse field longer, allowing the detector to determine the type of material that was found.

PI detectors have much more depth and work better in soil that is mineralized as VLF models, but they do not discriminate as well.

How to Buy a metal detector

As much research as you can on as many detectors as possible.

Know your area and what you find.

Know the limits of your favorite detector.

Go to store rental and a detector for a day. Its research capacity and then take it for a ride as you would normally. Its capacity, weight and comfort may surprise you.

Unit Name cheaper, more expensive, or brand can not be the best deal. Take time to compare the abilities.
